IEEE International Conference on Image Processing
作者: W.A.R.J. Weerakkody W.A.C. Fernando A.B.B. Adikari R.M.A.P. Rajatheva School of Engineering and Design Brunei University Uxbridge UK Telecommunications Programme School of Engineering Asian Institute of Technology Thailand
In this paper, we present a novel distributed video coding algorithm based on turbo trellis coded modulation (TTCM). As in the conventional turbo based Slepian-Wolf encoder, quantised information is applied to the TTC... 详细信息
